I'm running last version of Jukes (4.1.2.41) on an up-to-date Linux box Ubuntu 8.04 Hardy with Gnome desktop environment.One of the most lovable feature of Jukes, is that you can play a full album without making two or three steps cerating a new playlist before. But.Unluckely these feature works but it hangs Jukes as soon I try to do everything else (i.e. jumping a track forward) after giving that command ("Play Immediately"). My album continues to play, I can move the Jukes window, but I can't interact no more with Jukes. Also closing the window takes no effects.This is my output when launching Jukes from shell for debug purposes:

If I play the album by creating the playlist before, everything continues to work great.I have not the log of another Ubuntu 8.04 installed PC, but the beaviour is the same. Now I try with more debug verbosity as you suggested

I looked at where it got to when you said it froze and then I looked in the code. I have had a lot of trouble on different systems with that Spectrum Analyzer. I didn't write that code and it seems to cause threading GUI lockup problem in Jukes on some systems at times like Play Immediately. I develop on Windows and I thought I had fixed it everywhere but then Linux and Mac users have reported the random behavior like you are seeing so I just recommend to people to turn it off!
